Lens should honor kubectl.kubernetes.io/default-container annotation

[rittneje]

What would you like to be added:

When opening a pod shell or pod logs, Lens should abide by the kubectl.kubernetes.io/default-container pod annotation if present, instead of defaulting to the first container in the list.

Why is this needed:

This makes Lens consistent with the standard kubectl commands.
See https://kubernetes.io/docs/reference/labels-annotations-taints/#kubectl-kubernetes-io-default-container

Environment you are Lens application on:

• Kubernetes distribution: EKS
• Desktop OS: macos 11.6.5
